To all 'uffi om itu may concern;

Rockford. in the countyr offW'inn'ebago and State `of Illinois. haveinvented eertain' new Machines f for Preparing Tarps for-'Wearingof-whieh the following is a specifiation. r

On'eofthe''ohiects of this invention is the prmliuftion of 4a meehanismfor placing warp threads between the' splitsl of through the heddle eyes4of aV metallic' harness. l

The invention fu -tlier refers to means forsupporting the reed and forfeedilig it with relation to the drawingin merhanism.

'lhe invention also refers to a means for supporting the harnesses. andto a sensitivelyeontrolled feed for advaneing saidliarnesses withrelation to 'l`lie in verition for selerting :i 'single heddle in properrota.- ion from earh of the harnesses. am ing the hedwlle so seleetedwith itseye to-l ward `the dra wing-in needle.

'lhe ini'ention further refers'to an autr matie stop meehalusm adaptedto he aetupled,

when the heddle-seleeting meehanisln fails to grasp a he'ddle.

The invention also relates to the'produetion of improved means forholding a warp while the individual threads thereof are lleing operatedupon.

The invention further relates to the selee- -tiou of threads. singly'audsueeessivelv. from a warp. A l'urlher ohjeetol' th'e invention is toprovide means l'or severing 'seleg-led threads in ,order drawn in orotherwise operated upon.

.N further objeet is 'to provide means for stopping the marhinein easethe selerting means fails to taken thread from'the.l warp.

n the embodiment lrerein shown of this -inventio'n I provide asupporting frame comprisng'the bed 1 having the usual supporting legs 2.At the rear side of the bed andsecured to the rear face thereof are twoupwardly extending supporting arms 3, which arms at their upper endscarry two parallel guide rails 4 and 5 for the harness slides.

Below said rails and set off` (forwardly) fromlsaid supporting arms bythebrackets 6, the supporting arms 3 carry the guide bnr 7 havingagroove 8 formed in its upper edge and a guide Q for receiving andguiding the reed R (Fig. 6), said reed vlying loosely Within its grooveand guide. Each of the harness slides comprises a feed bar 10 (Figs. 21,22, 23, and 24) having ratchet teeth 11 formed in its upper face, eachof said feed bars resting upon the upper edge of one of the guide rails4 and 5 and being adapted to be slid lengthwise of said guide rails. Attheir ends upon their near sides the feed bars 10 carryharness-supporting hooks 12, withinwhich hooks the ends of' the harnessrods L are adapted to lie. Upon these harness rods are strung the steelheddlesl2.. In order to separate the heddles into small groups and toprevent their sliding to one end of their rods h I provide a spacer 13for each harness, said spacers consisting of two parallel side pieces 14held a little distance apart by rivets 15 set at frequent intervalsthroughout the length of the side pieces. The spacers are placed uponthe harness rods k directly beneath the guide rails 4 and 5, the rivetsl15 holding the heddles insuitable bunches throughout the length of saidharness-rods.

The ends of the warp threads (from the warp beam, not shown) to be drawninto the eyes of the harness and between the splits of the reed aresupported in a carriage 16 (Figs. l, 4 and 43) resting by` means of thefeet 17 upon alead-screw 18 and a rock shaft 19, said screw and shaftbeing alined and being supported adjacent to the front side of thebed 1. The Warp carriage leans against a short stationary ledge 20(Figs. 6, 7 and 12). The warp carriage 16 comprises the bowed arms 21secured rigidly together at their lower ends by the clamp 22 and theguardjplate 23, and near their middle portions by a bar 24. At theirupper ends the .arms 2l support a similar clamp 25, but

4outer edge.

. wise pivotally connected with rock shaft 26; thus when "said rock'shaft is oscillated by eitherl of the hand levers 29 the clamp is movedwith relation to.the clamp 22. The clamps 22 and 25 are uniform inconstruction. (Figs. 6 and 45.)

. Each comprises a channel-shape frame 30,

said frames being set to face away from each other upon opposite sidesof the carriagel 16. `llfrithin the frame 30 of each'clamp` two wedgebars 31 and 32 are placed, the adjacent faces of said-bars, beingprovided with i oppositely inclined wedging teeth 33. The

wedge bar 31 lies in contact with oneof the inner side walls of 'theframe 30, and is.

35 bymeansof an'insertion bar 36 over which `the .varp threads are laid.To bold the lthreads more firmly inthe clamp the insertion bar isprovidedfyith longitudinal ribs 37 (Fig. 6) adapted `to 4indent the rub-The wedge bar 31 ber facings 34 and 35. is moved longitudinally and theclamp thereby opened and closed by -means of a ever 33 pivotally mountedhy means of a stud 39 upon the inner side of the frame 3 0, and a togglelever 40 pivotally connectirg said lever 38 with a stud 41 on the wedgelbar 31.

The bar 24 projects rearwardly fromthe arms 21 beyond a straight linedrawn between the two clamps 22 and 25, and in its rear edge is formeda, longitudinal groove 42 (Fig. (5), in which groove lies a ribbon 43having a milled or otherwise roughened YVhen carriage 16 and clamped inthe clamps 22 and 25 thereof, they are bent over the roughened edge ofthe ribbon 43. When a warp has been ,so clamped, the clamp 25 is iovedaway from the clamp -22- by-turning the rockshaft 26, thus placing,rtension upon the threads, after which the thread-s are detlectedsidewise bctwccn'their points of support by moving the ribbon 43longitudinav in its groove 42 in the bal.' 24, which lon tudinalmovement is imparted to the ribbon by means of a lever 44"(Fg.43)pivotally mounted at the end ofthe har 24 and lil e the ribbon. Thepurpose of thus (leder-ting: the warp threads sdewise after they havebeen rlampcihand stretched in the warp carriageI is so that, when nachIndividual warp thread,

is released from the roughened edge of the ribbon 43 by the selector',

tend to straighten and move away from the Vbody of the warp threads,thus assisting' in the separation of the threads, A

rl"he warp carriage 1G 1s rclrasahly routhreads are placed in the saidthread shallI nected to the lead screw 18 by means of a half-nut 45earriedby anf arm 46 pivotally mounted on the carriage. (Fig.'44.) Inthe rear end of thearm 46 is rotatably supported an eccentric 47 Whilies Within an elongated4 opening 48 int e carriage, said eccentricbeing rotated by means of a milled hand-knob 49 (Fig. 43) to move thehalf-nat 45 into and out of engagement' with the sciew 18.

The 'screw 18 is intermittently rotated by means of a pawl 50 arrangedto en age a ratchet wheel' 61 which is ri id wit said screw. The awl 50is ivote on an arm 52 which is fixe to the roc shaft 19. A spring 53tends to hold the pawl in engagement with the ratchet wheel. The shaft19 is rocked by means of an arm 54 rigidw'ith the shaft and connected bya rod 55 to a crank disk 5G fixed Aon the drive shaft 57. On the Shaft57 is la 'ti' ht pulley 58 and a loose pulley 59 (Fig. 1%.

The means for sensitively controlling the feed of the warp carriage:omprises a finger 60 (Figs. 2 and 4G) suspended on knife-edge bearingsG0, lying in the path of the warp threads as the latter are presented tothe selector. The lower end of the finger 60 is curved to underlie-tberear end of the pawl 50. The rear end of the pawl comprises the partsl1/ and z, the latter extending farther to the rear than the former.l y

The operation of the warp feed is as follows: Assuming that the warp isso located with reference to the selector that a feed movement shalloccur, the lower end of the finger 60 is then in the position shown inFig. 47. The pawl 50 moves forward (to the left, Fir". 48), thereby'turning the ratchet wheelD through the distance of one tooth, and thusadvancing the waracarriagc. If the warp is thereby brought into properposition with reference to the selector'1 the pressrve of the foremostwarp thread against the finger (l0 causes the lower end of thc finger toswing into the path'of the harkward movement ol thepart z of the pau'l.As the pawl swings back, the part rides up on the finger GO, th cbyraising the forward end of the pawl .d iciently so that ou the nextforward stroke it will. not engage the next tooth of `thc ratchet wheel;heure the warp carriage will not be advanced. lrv the time tho removalof threads by tho schrtor or th(I sparing ol` the. threads nom-ssitatrsanother movement of thel warp rarriagc, thel lower end of the linger l0will have swung: ,out of the` path ol' the part s, so that therpawl mayengage the next tooth of theI ratchet wheel.
